Script to push (mirror) a large repo to GitHub

push-big-repo

#!/bin/bash -ex
#
# Push the current repository to GitHub, in small enough chunks that it
# won't exceed the pack-size limit

# Commit to start with, counting from the oldest.  If the process fails,
# you can change this variable to restart from where it failed.
START_COMMIT=1000

# Number of commits to push at a time, counting from the oldest.  If a
# push fails because the pack file is too big, try using a smaller number.
COMMIT_STEP=1000

git log --pretty=%H | ruby -e 'puts ARGF.each_line.to_a.reverse' > commits
COMMIT_COUNT=$(wc -l commits | cut -d' ' -f1)

for i in `seq $START_COMMIT $COMMIT_STEP $COMMIT_COUNT`; do
	echo ====== $i
	COMMIT=$(git show $(head -$i commits | tail -1) | head -1 | cut -d' ' -f2)
	git tag -d foo || true
	git tag foo $COMMIT
	git push -f origin foo
done

git tag -d foo
git push origin HEAD
git push --mirror

@mejuliver Is the repository you're pushing a mirror of something else? You can run git config remote.origin.mirror to find out. If it's true, you need to run git config --unset remote.origin.mirror to set it not to be.

You don't seem to be running the script with bash -ex that's in the #! line. If you do, it will show each command as it runs and will stop at the first error, which is also helpful for debugging.

using this git config remote.origin.mirror returns true so its a mirror repo
